What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

Phoibos Wave Master

Owners widely praise the Phoibos Wave Master for its attractive wavy dial, bright lume, and comfortable engineer bracelet, with many considering it one of the best-looking watches under $300. The watch features a sapphire crystal and ceramic bezel, and owners report good quality for the price, with a subtle wave pattern on the dial appreciated for its unique style. While some minor finishing flaws like slightly crooked hour markers or an off-center outer ring have been noted, these are generally considered not visible during wear. One owner experienced a clasp breakage after four years, but Phoibos replaced it free of charge. Some owners wish the watch were larger than 40mm, and one notes the GMT hand and other details may not hold up under extreme close-ups. Overall, owners rate the Phoibos Wave Master highly for its distinctive dial and value, especially considering its build quality and features.

From video reviewers

The unidirectional ceramic bezel action is praised. The lume brightness is noted as a weakness. Reviewers disagree on the water resistance rating, with some stating 300M and others 200M.

Yema Skin Diver CMM.20

Owners and reviewers widely praise the Yema Skin Diver CMM.20 for its vintage aesthetic, 39mm-39.5mm case size, and the in-house CMM.20 micro-rotor movement. The watch features a textured cream dial, sharp applied indices, and a satisfyingly over-engineered push-to-turn bi-directional bezel. The fully brushed bracelet with toolless micro-adjust clasp is highlighted as a significant improvement, though some note its extended lug-to-lug may challenge smaller wrists. Accuracy figures range from -3/+7 seconds per day to erratic results between 0 and -10 seconds per day, with a 70-hour power reserve. Some owners express concerns about the brand's QC reputation and the micro-rotor movement's performance, while one reviewer noted questionable finishing on a prototype's hour hand and a rattly clasp. Overall, owners and reviewers rate the Yema Skin Diver CMM.20 highly for its vintage styling and improved bracelet at the price.

From video reviewers

The sapphire bezel insert and in-house CMM.20 movement are noted strengths. Reviewers questioned the value proposition compared to other Yema models.
